It's fitting that St. Patrick's Cathedral would be on the same street with stores like Bergdorf Goodman, Tiffany & Co. and Van Cleef & Arpels. That's because for many people, shopping is a religious experience, and here between 34th and 59th streets you'll find the Holy Grail. Even if you're not planning to put your credit card to work at high-end stores, travelers say a stroll along Fifth Avenue is a must. "This may have been my favorite place in the whole city. The store windows all have such unique designs and are great for pictures," according to one TripAdvisor user.

Though some say Fifth Avenue's stores are too expensive to go all-out, the ritzier storefronts stand side-by-side with more reasonably priced shops like Gap, the Disney Store and Sephora. The stores on Fifth are somewhat mainstream, however; if you have a funkier style, head to SoHo.
